Lot Numbering Commands

Commands for numbering, ordering, and labelling lots on a survey plan.

R3NUMBERLOTS

Command: R3NUMBERLOTS

Auto-numbers all closed polylines on the active survey plan's Boundaries layer. Numbers are assigned sequentially starting from a user-specified number.

Usage

  1. Make sure a survey plan boundary layer is current (or only one plan exists in the drawing)
  2. Type R3NUMBERLOTS
  3. If lots already have numbers, you'll be asked whether to overwrite
  4. Enter the starting lot number (default: 1)
  5. Lots are numbered top-to-bottom, left-to-right based on their centroid position

Part lots

If polylines are marked as Part lots (via the ParcelType field in R3PROPERTIES) and share the same existing lot number, R3NUMBERLOTS keeps them grouped — all parts of the same lot receive the same new number.

R3ORDERLOTS

Command: R3ORDERLOTS

Re-numbers lots based on a polyline you draw through them. This gives you full control over the numbering order.

Usage

  1. Draw a polyline through the lots in the order you want them numbered — the polyline should pass through or near each lot
  2. Type R3ORDERLOTS
  3. Enter the starting lot number (default: 1)
  4. Select the ordering polyline
  5. Lots are numbered in the order their centroids fall along the polyline path

Part lots

Same as R3NUMBERLOTS — part lots sharing the same existing lot number are kept grouped and receive the same new number.

Tips

  • The ordering polyline can be any shape — straight, curved, or zigzag
  • It doesn't need to pass exactly through each lot, just close enough that the lot's centre is nearest to the correct position along the path
  • Delete the ordering polyline after use if you don't need it

R3ADDLOTS

Command: R3ADDLOTS

Places lot number text at the interior point of each lot on the plan's LotNumbers layer.

Usage

  1. Number your lots first using R3NUMBERLOTS, R3ORDERLOTS, or manually in R3PROPERTIES
  2. Type R3ADDLOTS
  3. Text is placed at the interior of each closed boundary polyline that has a lot number

What it does

  • Places a DBText entity at a guaranteed interior point of each lot (handles irregular shapes like battle-axe lots)
  • Text height is 5mm at print scale based on the current R3DWGSCALE setting
  • Text is placed on the plan's LotNumbers component layer (e.g. SP1_LOTNO)
  • Part lots are displayed with the PT prefix (e.g. "PT 51")
  • Single lots display just the number (e.g. "51")

Requirements

  • Lots must be closed polylines
  • Lots must have a LotNo set (via numbering commands or R3PROPERTIES)
  • Drawing scale must be set (run R3DWGSCALE first)
  • The plan must have a LotNumbers component (created automatically for new plans)

Part Lots (Multipart Parcels)

When a lot is split into two or more separate areas (e.g. a lot on both sides of a creek), each area is drawn as a separate closed polyline but they share the same lot number.

Setting up part lots

  1. Draw each part as a separate closed polyline on the Boundaries layer
  2. Number all lots normally using R3NUMBERLOTS or R3ORDERLOTS
  3. In R3PROPERTIES, select each part polyline and:
    • Set the Lot number to the same value for all parts (e.g. "51")
    • Set the Type to Part
  4. Alternatively, type PT 51 in the Lot field — R3Survey will automatically set the type to Part and store the lot number as "51"

How it works on export

When you run R3EXPORTLANDXMLNSW, part lots are automatically grouped:

  • A Multipart container parcel is created with the total area (sum of all parts)
  • Each part is exported with its own geometry and individual area
  • Parts are automatically suffixed with letters (e.g. 51A, 51B) — this is internal to the XML file and not shown on the plan

On the plan

  • R3ADDLOTS labels each part as PT 51 (not 51A/51B)
  • Each part has its own area shown in brackets on the plan
  • The total area is shown on one of the parts without brackets (standard NSW convention)

Typical Workflow

  1. Draw lots as closed polylines on the Boundaries layer
  2. Mark part lots — set ParcelType to Part in R3PROPERTIES for any lots that have multiple parts
  3. Number lots — run R3NUMBERLOTS for quick auto-numbering, or R3ORDERLOTS for specific ordering
  4. Adjust part lot numbers — give all parts of the same lot the same number in R3PROPERTIES
  5. Label lots — run R3ADDLOTS to place lot number text on the drawing
  6. Review — check numbers visually, re-run R3ORDERLOTS if needed
  7. Export — run R3EXPORTLANDXMLNSW — part lots are grouped automatically
